While you may not equate the online giant with fashion, over the past year Amazon quietly launched a number of in-house clothing brands. In addition to a child’s line called Scout + Ro, women’s label Society New York and men’s dress shirt line Buttoned Down, its latest push is into athleisure, or activewear.

The clothing section at Amazon.com is now bigger than its electronics catalogue. The number of clothing and accessory items offered on Amazon.com soared 91 percent in the last year to over 30 million items, according to analysts at the investment bank R.W. Baird. Research analyst Cowen and Company projects that Amazon could pass Macy’s as the No. 1 seller of clothing in the United States by next year.
